SEAL.

Specification of Letters Patent.

Patented Dec. 2, 1913.

Application filed September 23, 1912. Serial No. 721,732.

T '0 all whom it may concern Be it known thatI, EMIL TYDEN, a citi zen of the United States, residing at Hastings,'in the county of Barry and State of Michigan, have invented new and useful Improvements in Seals, of which the following is a specification, reference being had to the accompanying drawings, forming a part thereof.

The purpose of this invention is to provide an improved construction of seal of the sort comprising soft metal which is clenched onto a securing wire or cord.

It consists in the elements and features of construction shown and described as indicated in the claims.

In the drawings: Figure 1 is a perspective view of a seal embodying this invention shown with its securing wire in secured or sealed position. Fig. 2 is a section at the line, 2, 2, on Fig. 1. Fig. 3 is a sec tion at the line, 3, 3, on Fig. 2. Fig. 4L is a plan view of a hard sheet metal blank to form a part of the seal showing same with lugs and apertures preparatory to having the soft metal member cast upon it.

The seal shown in the drawings comprises a sheet metal element, 1, having cast upon it a soft metal element, 2, and engaged with both, a wire-securing member, 3. The hard sheet-metal element, 1, is in the form of a disk having its periphery suitably finished by hemming,that is, the edge of said disk being folded over and pinched down upon itself as seen in Fig. 2. Within the margin of this element there is formed an aperture, 4, preferably produced by striking up the metal partly to one side and partly to the other in the form of staple lugs, 5 and 6, for embedment in the soft metal element, 2, which is cast upon the hard metal element and rendered securely engaged therewith by occupying the aperture and embedding the lugs, 5 and 6. The wire member, 3, has one end portion coiled in a helix, 3 of suitable size to be inserted through the aperture, 4, of the hard metal disk and under the staple lug, 5, so that the axial aperture of the helix is situated entirely at the opposite side of the plane of the disk from that at which the helix is entered, and from which the remainder of the wire extends off through the staple lug, 6, past the edge of the disk. The soft metal element is cast upon the disk and wire after the latter has been located in the manner described under the staple lugs and in the aperture of the disk, and the soft metal boss, 2, formed upon the side of the disk at which the helix protrudes and is embedded in said soft metal, has an aperture extending through the coil of the helix.

In use, this seal will have the securing wire, 3, inserted through or around the package or look to be secured and then inserted through the aperture, 2, in the soft metal boss, 2 and therefore through the helical coil, 3*, on the other end of the wire. The boss being then clenched down upon the inserted end of the wire becomes then firmly engaged therewith, the helical coil of the wire which encompasses the inserted end of the latter being at the same time clenched uown upon the wire and effecting more secure engagement therewith than would be effected by the soft metal alone, and release of the wire by cutting through the soft metal DOSS is rendered difficult by the staple lugs, 5 and 6, of hard sheet metal.

The disk, 1, is designed to receive a permanent identifying mark, usually by initials of the transportation company or other custodian of the package protected by the seal. In addition to such permanent identifying mark, the soft metal bosses will receive a special imprint from the clenching pliers, as is usual in the use of lead seals.

I do not limit myself to the particular form consisting of a helical coil which is given to the embedded end of the wire member, 3. Any conformation of the wire by which it is given loops of any sort which protrude through the aperture of the hard sheet metal element and encompass the wire receiving aperture in the boss at the opposite side, would be within the scope of my invention in this particular.

I claim:

1. A seal comprising a hard metal disk, and soft metal projecting at its opposite sides occupying a limited portion of the area thereof, in combination with a securing wire having one end embedded in the soft metal at one side, the softmetal at the other side having an aperture extending through it substantially parallel to the plane of the disk for receiving the other end of the wire to be engaged therewith by compressing the soft metal thereon.

2. A seal comprising a hard metal disk having an aperture; soft metal occupying said aperture and extending in the form of a boss at one side and occupying a limited portion of the area thereof, in combination with a wire having one end embedded in the soft metal within the aperture and extending thence oif at one side of the disk, the boss at the opposite side having an aperture through which the wire may be inserted for engagement by compressing the soft metal thereon.

3. A seal comprising a hard metal disk having an aperture; a securing wire having one end portion formed with loops or bends entered in said aperture from one side of the disk and projecting therethrough, and soft metal in said aperture embedding said loops and forming a boss protruding from the side of the disk at which said loops protrude, said boss having an aperture extending through the loops for receiving the other end of the wire to be engaged by compression of the soft metal and wire loops thereon.

4. A seal comprising a hard metal disk having an aperture, and a lug struck out from and overhanging such aperture; a securing wire having one end portion entered in said aperture and having bends extending at one side of the disk under the over-hanging lug at that side, and soft metal in said aperture and embedding the wire and the lugs, and forming bosses protruding at opposite sides of the disk, the boss at the side at which said wire bends protrude having an aperture extending through said bends and in position to be overhung by the lug for receiving the other end of the wire to be received by the compression of the soft metal and lug and wire loops thereon.

5. A seal comprising a hard metal disk having an aperture and staple-like lugs struck out from said aperture on opposite sides; a securing wire having one end portion formed with loops or bends entered in said aperture from one side of the disk and proiectmg therethrough and under the staple-like lug at the opposite side, the other end portion of the wire extending through at the side from which such loops or bends are entered in the said aperture and out under the staple-like lug at said side, and soft metal in said aperture and embedding said lugs and loops, and forming bosses at the opposite sides of the disk, the boss at the side of which said wire loops are embedded, having an aperture extending through said loops for receiving the upper end of the wire.

In testimony whereof, I have hereunto set my hand at Chicago, Illinois, this 12th day of September, 1912.
